Continuity mistake: The girls are driving when they see Karen driving the van Martina. Problem is: when the girls stopped, there was a stop sign, but when they drive on, the stop sign is missing.
Audio problem: When everyone is leaving the restaurant and walking down the street, some are going off for a night cap, Rosemary says she can't go because she has to work tomorrow. But her words and her mouth are out of sync, as are the others to a lesser degree.
Continuity mistake: When the girls walk into the palm shop, Rosemary's sleeves are rolled down to the wrists, but, a second later, just as she gets a large spider on her arm, her sleeves are rolled up to the elbows, so now the spider can bite her.
Continuity mistake: As they are sitting around, discussing what to do after Charlie's death, Bobby, in the long shot, is just sitting there, but, in the close up, she is holding the ends of her hair against the wind.
Continuity mistake: While the girls are packing up Charlie's belongings after he died, Rosemary brings out the small bag from the bathroom. Laura is seen rummaging around in the bag, looking for Charlie's auto-injector, but she just moves them around, until the next shot, where she suddenly has half of the items out of the bag and in her hand.
Continuity mistake: In the beginning, Rosemary is riding on the back of a motor scooter. Problem is: when the green screen is being used, Rosemary's jacket is light-brown, and when stunt doubles are being used and it's not a green screen her jacket is now dark-brown.
Continuity mistake: Near the end, the killer, with his pistol, is 3 large steps away from the narrow road, but when Rosemary comes by on the motor scooter he's somehow close enough for her to knock the pistol out of his hand.
Continuity mistake: When Bobby approaches Ray about money, as he comes down the stairs she has a bag over her right shoulder, but in the next shot the bag is gone.
Continuity mistake: When the big palm tree is being installed, Laura is giving instructions from down below, but depending on the direction of the shot - from down below or up above - Rosemary is missing half the time.
Character mistake: When Laura attempts to feel Karen's pulse on her carotid artery, after the van rolled down a hill, she says she's dead; unfortunately, Laura's fingers are too high on Karen's neck; the carotid artery is deep into the middle of the neck, not high up.
Continuity mistake: When the girls are loading the truck with plants for the second time, they are told that the big palm tree will be delivered tomorrow. But there are 4 smaller palm trees that magically appear - the girls didn't take them in their truck and they weren't delivered, but they're there.
Continuity mistake: When Bobby corners Ray at the bottom of the stairs, which, I assume, lead to Ray and Blanca's private quarters, there is a swimming pool behind Bobby. At first, there's no-one near the pool, but, in the next shot, there are people dangling their feet in the water and a man asking Ray for the papers, plus more.
Other mistake: When Laura is directing the planting of a very large palm tree, she says something in Spanish and points to her left; but the man installing the palm moves it to the right - the exact opposite - but suddenly it's perfect.
Other mistake: When Rosemary is bitten by a spider, Laura says how pretty it was, with red and black stripes on its abdomen. Problem is: we don't get to see its abdomen - Rosemary wipes it away with her hand - and all we saw was black, no red in sight.
Answer: Regents park.
